Abstract

First, it should be clarified that what we are doing in this work is not now-casting, but rather hind-casting. Given the observed radar estimates and station data (some weather condition that has already existed), we try to estimate the true rainfall field. Since we are not forecasting, we do not simulate time series of precipitation. With the high spatial resolution of radar estimates, e.g., (1 km X 1 km), or even (500 m X 500 m), the acquisition of QPE with high spatial resolutions is possible. Then how to obtain QPE with relatively high time resolutions? Though this work discusses only spatial simulation (or QPE in hind-cast mode), the hind-cast can be made at fine time resolution (every 10 min, or even 5 min). Given the above, one could say the QPE is obtained at high spatiotemporal resolutions.
